TYPE-WRITING MACHINE.

SPECIFCATIGN forming part of Letters Patent No. 289,489, dated December 4, 1883.

Application filed March 30, 1882.

To @ZZ whom 2S may concern.-

Be it known that I, J osmrr L. YOUNG, of Tarrytown, Vestchester county, and State of New York, have invented a new and useful 5 Improvement in Type-Writers, of which the following is a specification.

The invention relates to a type-writerso constructed that the operation is performed by moving a wheel or segment of a wheel, with raised letters or characters on its edge, over the surface of the paper. Over this wheel or segment is an index-wheel, upon which are placed the letters or characters corresponding to those on the type-wheel. These wheels are, connected by a bevel-gear, and are moved together by an arm, which is pivoted to the center of the index-wheel. The outer edge ofsaid projections or notches, with spaces between. These spaces are numbered or lettered the same as the numbers or letters on the type-wheel. By moving this arm i to the letter desired on the index-wheel, and carrying it around to the delivery-post, then pressing down the lever on which the typewheel and-index-wheel are placed, the desired letter is printed or impressed on the paper.

In the accompanying drawings, in which similar letters of reference indicate like parts,

Figure l is a longitudinal view, partly in section. Fig. 2 is an end elevation, partlyin section; Fig. 3, a top view.

In the drawings the frame is letter A, Fig. 1.

B is a guide strip or track extending across This guide-strip is raised a little above the surface of the frame, to allow the paper C, which rests on frame A, to pass or move under it. The sides of said frame are grooved, and the ends of the guide-strip are tongued, so that the guide-strip maybe moved to any desired longitudinal position on the designated by frame A. The grooves are markedD. Y Upon the guide-strip B is placed carriage E. This carriagemoves along the guide-board B atregular spaces. These spaces or distances are regu lated by a ratchet and pawl, or its equivalent, (marked F,) which catches into one of a line of perforations on the guide-strip B, `(marked G.) Vhen ratchet F is pressed, the pawl, catching 5o in the perforation, produces aleverage,which forces the carriage E to the next hole or per- Vhen this movement ofthe carriage foration.

(No model.)

is made the leverI-I is lifted above the paper. By repeating the pressure, the carriage E may be moved to any space or perforation on the guide-strip B. These perforations are at exact distances apart. A raekgear or other appropriate equivalent might be employed to move the carriage.

I-I is a lever pivoted at I to the carriageEat its outer end, and perpendicular to its side is fixed the type-wheel J. The alphabet or symbols are raised upon the edge of this wheel or disk.

On the top of lever H, and at right angles to the type-wheel, is placed the index wheel or disk K. The edge of this wheel is turned upward or vertical from its plane, and is divided into projections and spaces marked a a. These spaces are equalto theletters on the type-wheel, and correspond with them. By means of bevelgear L and L2 or other connection, the typewheel and index-wheel move together, so that the chosen letter on the index -wheelK is printed on the paper C by type-wheel J. The arm M is pivoted in the center of the index wheel or disk, and is jointed, so as to be easily lifted above the projections and spaces a a', and can be moved around the disk in either direction.V

In operating the machine the movable arm is placed in the space marked by the letter desired to be printed. This arm (marked M) is stopped at a fixed post marked N. This post is provided with a slot, O, into which the arm M drops. The lever H is then pressed downward at the printing end and the letter delivered upon the paper. The arm M is again moved to the space desired, and brought around to the fixed post N, bringing or revolving the disk as before, which in turn, by the :agency ofthe bevel-gears, also revolves the type-wheel. The lever H is again pressed upon the paper, and the printing performed as before. After printing a letter, the pressure of the hand on lever II is slightly relaxed,which allows spring P or its equivalent to lift the printing end of lever H above the surface of the paper. As it lifts, the ratchet F is operated, which instantly carries the carriage E to the next required space by means of the pawl Q, Fig. 2, catching into the hole or perforation Gr on guide-strip B. The rollerS wheel with printers ink or its equivalent.

R and B2 are feed-rollers on the top of frame supplies thetype IOO A, used to carry the paper longitudinally from line to line. One of these rollers, R2, is placed flush With the top surface or plane of frame A. The other (marked R) is placed above itin appropriate position. The upper roller is covered or supplied with bands of rubberV or other equivalent to facilitate the feeding ofthe paper. I also use rollers B B2 as a clamp to hold paper in position when I use the grooves D to change the position of the guide-strip B.

1. In a type-Writer, the guide-strip B, in combination with the carriage E, type-Wheel J, index-disk K, arm M, post N, with its notch O, and bevel-gears L L2, substantially as described.

2. In a type-writer, the combination ofthe type-Wheel J, indexlisk K, and arm M,with the lever H and bevel-gears L and L2, substan- JOSIAH L. YOUNG.
